The Dell UltraSharp U2713HM is the latest addition to the UltraSharp line, and like its predecessors, it rocks. It uses a 27-inch IPS panel, only this time it`s an AH-IPS panel rather than a P-IPS panel, and it uses LED backlighting instead of CCFL backlighting. While delivering excellent color fidelity, it uses less power than several recently reviewed IPS displays."
